A source said time has been booked in the Cedar Rapids and Des Moines markets. There's some confusion as to whether the commercials are coming from Perry's campaign or from the pro-Perry super PAC, Make Us Great Again. We've sought clarification from both camps.

The ads would come as part of a larger Perry campaign move to reclaim momentum in the race. The Texas governor has added a team of national advisers — including pollster Tony Fabrizio and media consultants Curt Anderson and Nelson Warfield — and plans to give a speech Tuesday outlining a proposal for a national flat tax.

UPDATE: Two sources told us that the ads are coming from the campaign itself, and not Make Us Great Again.

Perry's top strategist Dave Carney had indicated prior to this week that the first spots would likely be introductory/biographical about Perry, although it's unclear what the initial ads are.

UPDATE II: A source tells Ben that the ads are a weeklong buy and airing statewide.

Three independent sources confirmed to POLITICO that time had been been bought in several markets statewide in Iowa. Typically ads go up when the time has been purchased.

However, sources said the stations had yet to receive a spot, and that it's possible that the ad blitz could start later in the buy window.

The time orders were placed by Paint Creek Productions, on behalf of Perry's campaign, according to a source familiar with the order, who added that the buyer was Crossroads Media. Neither could be confirmed immediately.
